CARBURETER.

Specification of Letters Patent.

Patented Dec. 19, 1916.

Application filed January 3, 1916. Serial No. 70,073.-

To all whom it may concern:

. Be it known that I, CHARLES C. MANKER, a citizen of the United States,residing at Ogden city, Weber county, Utah, have in vented a new anduseful Improvement in Carbureters, of which the following is aspecification.

My invention relates to carbureters and more particularly to acarbureter for carbureting air.

An important object of the present invention is to provide a carburetorwhich thoroughly carburets the air.

A further object of my invention is to provide a carbureter and meansassociated therewith whereby the degree of richness of the gas may bevaried. I

Another important object of this invention is to provide a carbureterhaving a buoyant mixer associated therewith.

An additional object of my invention is to provide a durable carbureterwhich consists of few parts and is inexpensive to manufacture and whichmay be placed on the market at a comparatively low cost.

The above and other objects and advantages of my improvement will fullyappear from the following description, taken in connection with theaccompanying drawings and be explicitly defined in the appended claims.

On the drawings, Figure 1 isa longitudinal sectional view of acarbureter. Fig. 2 is a top view of the carbureter. Fig. 3 is alongitudinal sectional view of the buoyant mixer, and Fig. 4: is a viewof the buoyant mixer taken on the line -1-4 of Fig. 3.

Like characters of reference indicate like parts in all the views.

The numeral 5 denotes the carbureting chamber. Projecting from the topof the carbureter chamber is a tubular guide 6 having a plug 7 threadedinto its upper end. Extending from the chamber 5 adjacent the bottomthereof is a threaded nipple 8. Threaded on this nipple 8 is a T-shapedconnection 9. Threaded into one end of this T-shaped connection 9 is avertical pipe 10 having a valve chamber 11 therein which is providedwith valve seats at both ends. A ball valve 12 is arranged within thisvalve chamber 11. This pipe 10 serves as a means whereby the chamber 5is filled with hydrocarbon. It will be seen that the chamber 5 may beonly filled to a certain level owing to the valve arrangement in thepipe 10, thus obviating the danger of entirely filling this chamber.Threaded into the outer end of the connection 9 is a drain plug 13whereby any sediment or the like may be drained from the chamber 5.

' Mounted within the chamber 5 is a U- shaped pipe 14:, one end of whichextends above the top of the same, as indicated at 15. The end 16 ofthis pipe extends within the tubular guide 6. This U-shaped pipe 14conveys air under pressure from any suitable air compressor to theinterior of the chamber 5.

The numeral 17 denotes a buoyant mixer in general, As this mixer is animportant part of my invention, it will be set forth in detail. T hisbuoyant mixer embodies a bottom wall 18 and a vertical wall 19.Connecting the bottom 18 and the upper edge of the wall 19 is aninclined wall 20, thus providing an annular float. This inclined wall 20provides a substantially conical cavity. Extending centrally through thebottom 18 is a relatively large tube 21 havin g openings 22 adjacent andabove the bottom 18. This tube 21 is telescopically engaged on the end16 of the pipe 14. The upper end of this tube 21 is closed as at 23.Mounted upon this closed end 23 is a vertical stem 24. Carried by thetube 21 are collars 25 and 26.

The numeral 27 denotes longitudinally curved blades having securing tabs28 thereon which are riveted or otherwise secured to the collars 25 and26 as at 29. These blades are beveled, as at 30, from their upper outeredges to their lower inner edges so as to'fit within the conical cavitThese blades are relatively wide at thelr inner ends.

Between the collar 26 and the lower end of the wall 20 and around theopenings 22 is a chamber 31 where the air and hydrocarbon meet. Mountedupon the tube 21 is a deflecting plate 32 which causes the mixture toflow outwardly between the blades.

Mounted upon the stem 24. are weights 33 which are for the purpose ofregulating the richness of the mixture. It will be seen that by addingmore weights the buoyant mixer will be moved deeper in the hydrocarbonwhereby a rich mixture is produced,

and that by detracting the weightsthemixer moves toward the top of thehydrocarbon whereby a less rich mixture is produced.

An outlet pipe 3i'is mounted in the upper end of the chamber 5 which isadapted to be connected with the service pipe or with any suitableconnection to convey the miXture to any container.

In the operation of this apparatus the chamber 5 is filledwith-hydrocarbon which flows in the open end of the pipe 21 and outthrough the openings 22 and into the chamber 31. Compressed air is nowforced through the pipe 1% which strikes the closed end 23 of the member21 and is deflected downwardly, thence it escapes through the openings22 and into the chamber 31 which contains some of the hydrocarbon. Thiscompressed air agitates the hydrocarbon which is contained'in thechamber 31 and thereby thoroughly vaporizes the same. Ast'his-carbureted air flows into the chamber 31 it forces the hydrocarbonthat is contained therein against the blades 27 and as the'air issuesbetween the blades it thoroughly vaporizes the hydrocarbon that hasadhered to the *same and. at the same time rotates the mixer 17.

Frointhe foregoing description taken in connection with the accompanyingdrawings the advantages of the construction and method-of operation willbe readily understood by those skilled in the art to which theinventionappertains, and while I have described the principle of operation, together with the form-of the invention which I now consider to be thebest embodiment thereof, I desire to have it understood that theformshown is merely illustrative and that such changes may be made whendesired as fall withinthescope of the appended taining chamber, of aU-shaped pipe mounted within the chamber for conducting airthereinto, atube telescopically engaged with the inner endof the U-shaped pipe andhaving its-upper end closed, a buoyant member fixed to the tube andhaving a cavity in its upper face thereof, the bottom of said cavityconstituting a liquid fuel containing chamber, and a' plurality ofblades fixed to the tube and positioned within the cavity.

2. The combination with a liquid fuel containing chamber, of a U-shapedpipe mounted within the chamber for conducting air within the same, avertically movable tube telescopically engaged with the inner end of'the U-shaped pipe and having its upper end closed and its lower endperforated, a buoyant member secured to the lower end of the tube, theupper face of the buoyant member being provided with a relatively largecavity, the bottom of the cavity constituting a liquid fuel holdingchamber, and a plurality of blades fixed to the tube and positionedwithin the cavity.

3. The combination with a liquid fuel containing chamber, of an airconducting pipe mounted therein, a tube telescopically engaged with thepipe having perforations at its lower end, and its upper end closed, anannular buoyant member secured to the tube adjacent the perforations andhaving a relatively large conical cavity in its upper face, the bottomof the cavity constituting a liquid fuel containing chamber, and aplurality of curvedblades extending radially from the tube adapted torotate said tube and buoyant men'iber upon the injection of air in theair conductingipipe. 7
